Key Benefits

Ultra-Fine 16.5μm Merino Fibers:** Utilizing exceptionally fine 16.5-micron wool, this garment offers a delicate, "soft-cloud" texture that eliminates the scratchy irritation typically associated with traditional wool products.

Advanced Moisture Management:** Designed for high-intensity movement, the fabric naturally wicks sweat away from the skin and dries rapidly, keeping you dry and preventing the post-exercise chill.

Natural Thermal Regulation:** Merino wool is nature’s smart fabric, providing superior insulation in freezing temperatures while remaining breathable to prevent overheating during peak activity.

Luxurious Skin Contact:** The refined weave ensures a luxurious wearing experience, making it comfortable enough for all-day use directly against the skin without any "stinging" sensation.

Versatile Athletic Fit:** With a sleek, fashionable design, this piece functions perfectly as a technical base layer under a ski jacket or as a standalone performance top for autumn running and training.

How to Use

For optimal performance in extreme cold, wear this garment as your primary base layer directly against the skin. It is designed to be paired with a mid-layer (such as a fleece or down vest) and a waterproof outer shell for skiing or hiking. For high-output activities like running in cool weather, it can be worn as a single layer to manage sweat and maintain core temperature. Ensure the fit is snug against the body to maximize the moisture-wicking properties of the wool.

Care & Safety

To preserve the integrity of the 16.5μm wool fibers and maintain the garment's shape, it is recommended to wash this item on a gentle cycle using a wool-specific detergent. Avoid using bleach or harsh fabric softeners. For best results, air dry the garment flat to prevent stretching and keep it away from direct high-heat sources like radiators. Store in a cool, dry place to protect the natural fibers from moisture.

Notes

This garment features "16.5μm羊毛" which provides a "细腻软糯" feel that is exceptionally soft and comfortable against the skin.
